Factory & Commercial Solar

Turn rooftop square metres into a 20-year revenue stream.

Commercial and industrial solar that actually matches your load curve, your demand charges, and your tariff structure. Designed by engineers who've read your utility bill first.

Who this is for

Factory operators, warehouse owners, commercial landlords, and industrial estate managers. Anyone with meaningful roof square-footage or land, a daytime load profile, and an electricity bill large enough that a 20–30% reduction is worth the capex.

The numbers we actually care about

Residential solar is mostly a kWh conversation. Commercial solar is a capacity, demand-charge, and load-matching conversation. Before we quote a system, we want to see:

  • 12 months of billsPeak demand, time-of-use rates, power factor penalties, and any seasonal tariff variation.
  • Daytime load curveWhat you actually draw at 2pm vs. 8pm. This determines how much solar you can self-consume.
  • Production hoursSingle-shift, double-shift, 24/7. It changes everything.
  • Utility export rulesNet-metering, net-billing, or self-consumption only. Each regime wants a different system size.

What we supply

  • Feasibility studyStructural load analysis of the roof, shading study, production model, and financial model (IRR, NPV, payback) before any design commitments.
  • Turnkey supplyEngineering, procurement, and coordinated installation through our partner network — as one contract, one point of accountability, one warranty backing.
  • Utility-scale componentsTier-1 bifacial panels, string or central inverters sized with thermal headroom, string monitoring or module-level optimisation where shading demands it.
  • Commissioning & testingIV curve testing, thermal imaging, and string-level commissioning reports delivered on handover.
  • O&M service contractOptional but recommended — scheduled inspections, panel cleaning, string-level performance monitoring, and guaranteed response SLAs on faults.
  • Financing structuresCash purchase, loan, operating lease, or PPA (power purchase agreement) — each has different balance-sheet and tax implications; we'll walk through which fits your situation.
PPA vs. owned system

A PPA puts zero capex on your balance sheet but also gives up 20+ years of savings to the PPA provider. An owned system has higher upfront cost but captures the full economic return. Which is right depends on your cost of capital, tax position, and how long you plan to occupy the site. We'll model both.

Structural considerations

Not every commercial roof is a good solar candidate. Older roofs near end of life should be replaced first — installing solar on a roof that needs replacing in 5 years costs twice. Metal roofs are generally easier than concrete; concrete can still work with ballasted or mechanically-fixed mounting systems. We include a structural assessment in the feasibility study and flag it openly if the roof needs work.

How the process runs

  1. Initial engagement. Call or site visit; review bills and discuss objectives.
  2. Feasibility study. Site survey, structural assessment, yield model, and financial model. Delivered as a written report.
  3. Design & proposal. Engineered system design, full bill of materials, commercial terms.
  4. Financing structure agreed. Cash / loan / lease / PPA — whichever fits.
  5. Contract & milestone payments. Transparent payment schedule tied to project milestones.
  6. Procurement. Components ordered with tracked lead times.
  7. Installation. Typically 2–12 weeks on site depending on system size.
  8. Commissioning & utility connection. IV curves, thermal imaging, signed commissioning report.
  9. O&M phase. Ongoing monitoring and scheduled maintenance.

Frequently asked

Most commercial systems in Asian markets pay back in 4–7 years, with internal rates of return in the 15–25% range. The spread depends heavily on tariff structure and how much of the production you self-consume versus export. The feasibility study includes the specific numbers for your site.
Possibly. Modern solar systems add roughly 15–20 kg per square metre, well within the structural capacity of most commercial roofs, but older structures or damaged roofs need to be assessed. The feasibility study includes a structural review. If the roof won't support the load or is near end of life, we will tell you before you spend money on the project.
Production drops — typically to 20–40% of rated capacity on heavily overcast days — but you're still buying less from the grid. The annual yield model accounts for cloud cover and seasonal variation specific to your location. What matters is annual production, not any single day.
Yes, and it's often the right approach. We can design a phase-1 system that uses part of the roof with infrastructure (inverter capacity, cabling, switchgear) that accommodates later expansion. Committing the whole roof in phase 1 isn't always the best economic answer.
Yes, grid connection applications and utility approvals are part of our turnkey scope. Timelines vary significantly by utility and country — we'll give you a realistic timeline during the feasibility study based on the specific utility you're connected to.
